Response: Prevalence and Risk Factors of Gastroesophageal Reflux Disease in Patients with Type 2 Diabetes Mellitus (Diabetes Metab J 2016;40:297-307)

We thank Dr. Yi for his comments in response to our study, "Prevalence and risk factors of gastroesophageal reflux disease in patients with type 2 diabetes mellitus" [1]. Prevalence of gastroesophageal reflux disease (GERD) in Korea has gradually increased after westernized diet and lifestyle changes [2]. The prevalence of GERD in our study showed 32.6% in the type 2 diabetes mellitus (T2DM) group and 35.9% in the control group. We mentioned that the possibility of overestimation of the prevalence and symptoms of GERD cannot be ruled out by selection bias.
